FUSE BOX.

Application filed September 22, 1919. fierial We. SHAWL '1 '0 all whomit may concern:

Be it known that I, Aoonrn OLnvIN, a citizen of the United States,residin at Detroit, in the county of Wayne and tate of Michigan, haveinvented certain new and useful Improvements in Fuse Boxes, of which thefollowing is a specification.

My invention relates to improvements in fuse boxes, and has for itsprincipal object to provide a box of non-inflammable material that canbe quickly assembled or disassembled at the place of use.

Another object is to improve the construction of fuse boxes by providingan all-metal box with interfitting projections and grooves which can beconveniently clamped .into position for use.

A further object is to provide a fuse box of simple and inexpensiveconstruction, composed of parts not liable to be harmed by exposure tothe elements and not subjected to strain or wear.

Other objects and advantages will be apparent from the followindescription, in which reference is had to t e accompanying drawingsillustrating a preferred embodlment of my invention and in which similarreference numerals designate similar parts throughout the several views.

In the drawings Figure 1 is a perspective view of a fuse box constructedin accordance with my invention;

Figure 2 is an enlarged detail elevation of one of the interfittingprojections and grooves;

Figure 3 is a plan view of the clamp shown in position in Figure 1; and

Figure 4 is a diagrammatic view of the walls of the fuse box indis-assembled posi tion.

In the drawings, the numeral 5 designates a blank of resilient metalprovided along one side with extensions 6, preferably formed in keystoneor dovetail shape and on the other side with correspondinglyshapedgrooves 7. This blank 5 is adapted to form the bottom and the two endwalls of the fuse box, being bent along the dotted lines shown in Figure4 when 1n use. At each end of the blank 5 is referably formed anapertured tab 8 whereby the box can be conveniently secured in positionagainst the wall or other desired place of use. One side wall 9 isformed with grooves 7 adapted to receive the keystone-shaped projections6 of the bottom and end walls of the blank 5, while the other side wall10 is provided with keystone or dovetail-shaped projections 6 adapted tofit into the slots 7 of the bottom and end walls. When desired for use,the end walls are bent upwardly from the bottom wall into substantiallythe position shown in Figure 1, and, being made of re silient material,can be sprung outwardly to a slight extent to facilitate the positioningof the side walls 9 and 10, which are placed close to the edges of theend walls and the projections snapped into the corresponding grooves.

To insure the holding of the side walls in position, I preferably rovideone or more clamps 11 shaped pre erably as shown in Figures 1 and 3 andhaving a body portion provided with slots 12 adapted to fit over screwsor pins 13 suitably secured in the end walls of the box and also havinga pair of downturned flanges 14 which engage the outer edges of the sidewalls 9 and 10. One or more openings ,15 are also placed in the bodportlon of the clamp to enable the rea (1y fastening of the device toany desire object.

To enable the grouping or gauging of several boxes in close relation, Imay form in the side Walls a depression 16 (see Figure 2) ofsubstantially the same depth as the width of the clamp and into whichfit the flanges 14 of the clamps. In this manner a smooth side wall issecured which will fit flush against the adjacent wall of the next boxin the group. If desired, the clamps can be so placed that the flangesengage the end walls of the box instead of the side walls.

While it will be apparent that the illustrated embodiment of myinvention herein disclosed is well calculated to adequately fulfill theobjects primarily stated, it IS to be understood that the invention issusceptible to variation, modification and change within the spirit andscope of the sub'olned claim.

aving described by invention, I claim:

A fuse box having bottom and end walls formed of a single piece ofresilient metal and provided with keystone-shaped grooves along theedges on one side of the bottom and end walls, and similar projectionsalong the opposite edges of said portions, a side wall provided withkeystone-shaped grooves adapted to interfit with the projections on thebottom and both end walls, a second side wall provided withkeystone-shaped projections adapted to fit into said grooves in thebottom and both end walls, and a clalnp adapted to engage the side wallsto maintaln them in position, the side walls being provided with notchesto receive the ends of the clamp of sufiicient depth to maintain 10 theouter edges of the clamp in substantial alignment with the outer surfaceof the side Walls.
